ALPLIUATION I ILED NOV. 26,1907.

a SHEETSSHEET fig i 7 ing motion for the purpose well understood may be lowered sufliciently'to free thebail frame being thus freed from the smaller-parts above, this side frame is supplied with the (ribs QLadapte'dWhen the casting is in posii jthe c entral};'iqpening of the side frame. ,enlarged o enin'gQ 22, isjof'sufficient depth, as is clea'rlyi ustratedorrtheldrawings, to percaSting EQQ to-be withdrawn sidewise njj'oh'laterally of -the side frame after the springs 15" h'i'nto the-enlargedpa'rt of the opening. Rest- .ingdnthe alined seats or sockets 28 are the. .o.ppositely-extended ends I or trunni'ons 31 v ot afsubstantially U-shaped bail 3 2-, over the lower horizontal rounded central part 33 of bolster 34, equipped at each end on its-under surface witha transverse groove or recess 35 ,adapted to receive a portlon of the ball located bolster and spring opening 39 wit stantiauysemi cylindrical sockets 28, while the outerffacejof each of the walls 27 is suppliedlwith'a pair of parallel vertical guiding hes 'de frame to eo-act with the inner er'faces of the portions30 of the side fi which constitutethe columns thereof an form theverticalmargins or boundaries oftheupper restricted or reduced portio%}pf havebeen takenout and the casting lowered which is adapted to fit the end of a truck indicatedf ln other words the end of the bolster hooks over the lower portion of the bail whereby to giveto the bolster a swing in this art,.and to limit the lengthwise shifting or travel of. the bolster I provide the top surface of each end of 'the same with an upstanding stop 36, [braced by -one or more brackets 37 and; adapted to strike against the upper portion of the side frame to limit and restrict the movement of .the bolster..

It will be readily understood that the partsv of the truck may be conyenientlypdisassociated and the bolster removed byfirst lifting the weight from the springs 24 and taking the same out of theside frame whereupon the casting 25 and the bail supported thereby from the bolster, and upon further lowering of the parts into the enlargement 22 the casting 25 and .the bail may be readily withdrawn sidewise from the side frame, as is obvious. The central opening of the side permits lengthwise withdrawal of the bolster therethrough.

In the modincatlon illustrated in Fi s. 4, 5 and 6, the side frame 38 has a centra 113;

straight vertical edges 40 forming columns of the-side frame, no enlarge ent of the opening. 39 being provided in t liis instance. As in the embodiment of my invention described usual and ordinary springs 24, upon'the top ends of which is seated a bolster supporting casting 41 having a horizontal plate portion 42 and upstanding end walls 43-, -eaeh :of which is supplied on its outer face with a single inner'vertical guiding rib, 44 adapted to resting thereon cooperate withthe inner faces of the columns .40 to. prevent outward movement of the casting and guide its vertical reciprocations; At its upper end each of'these walls 43-has a semi-'cy ends of which are closed by the walls 43, fas

is clearly indicated in Fig. 5. A cylindrical,

ndrical socket or seat 45, the outer shaft or rod. 46 of the proper length has its if ends resting in and supported byra pair of alined seats 45, and the shaft or rod passes through the upper apertured orperforated ends of a swinging bail 47, over the lower horizontal connecting .portion'of which'the end of the bolster 49 is adapted to be hooked,

previous instance, so that the two as in the bails on t e op osite sides of the truck bear the entire weig t of the bolster and the load It will be apparenttnat since the weight is taken off of the springs 24 they maybe readily removed from the side frame, whereupon the' bolster may be easily unhooked from the bails supporting" its opposite ends, where-v upon the pair of castings'41 of the truck may.

be taken out-inwardly of the side frames, as I is obvious, then the bolster may be withdrawn lengthwise through either of the openings 39 of the two side frames In the construction illustrated in Figs. 7 and 8 the side frame 38 is like that shown in Fig. 4, and .the bolster su porting casting 49 with the single guiding 1'1 50 at its opposite ends is substantially like'the castin 41, except that atthe top of each end wal 51 lindrical boss or stub shaft 52 integral with the .end wall and having a hole 53 extended there is-provided an inwardly-extended 0y therethrough. On these alined" bosses or f supports 52 is hung a bail 54' substantially like the bail 47, cotter pins 55 passing through the holes or a ertures 53 maintaining the bail in place. 11 order tomount the bail inv position, its parallel legs. areibent together somewhat and then spread a art so thatthe projections 52 fit in the alined gytials or apertures at the upper endssof the The only difference between the car truck construction shown in Figs. 9 and; 10' from that illustrated in Figs. 4, 5 and S is thatthe' I bail and its supporting shaft are cast integral was to form a single unitary iec'e 56having oppositely-extended rounds .terminaL- por-L tlons 57 ada ted to be seated and the sockets 45 o the casting 41 illustratedinFig.

10, which is in all respects like that shown in Fig. 5.

In Figs. 11 and 12 I have slif a oon" struction in which the bQIster 'hup orting casting 58 has on the outer face of eac of its, end walls. '59 a single vertical guiding 111260,

the upper ends of the walls being connected .bY 8 round shaft or rod 61- inte al with the casting 58.; On this rod or she. is adapt ed,

' sup orting castings to'be hung a bait-62 having hook-shaped ends 63 adapted to be'hung as is clearly shown in Fig. 11.

The method of removing the parts from the side frame is obvious from theillustifaf tion and description given above. It is to be understood, however, that'any of the bolster illustrated. and descri ed may, if desired, have on each end a pair of parallel column guide ribs, in which case it is necessary to employ thecasting in connection with an enlarged opening side frame of the general type shown in Fig. 1. Also if desired the casting 25 shown 'inFi'g. 5 may have only one uiding rib on eachend, in which instance side frames with apertures having vertical margins, as illustrated in Figs. 4, .7, 9 and 11,-may be used in the car truck. I Although I have described with some'degree of particularity a variety of embodiments of my invention, it is to be understood that my invention is not limited to the precise structural details of any of these species, since .the

' devices may be modified in minor details without departure from the-substance invention or the sacrifice of any of its fits or advantages.

Y I claim:

1. In a railway car truck, the combination of a side frame, one or more springs, a bolster support resting on said spring orsprings and havl, 1g one or more column guldes co-actmg witlntsaid frame, a bolster, and means sup po; ting said bolster-swinging on said bolster support, substantially as described.

2. In a railway car' truck, the combination of a side frame, one or more springs, a bolster of my beneon the shaft 61,

avmg one or more column guides co-actin with said side frame, a bolster, and a bai hung on said bolster support which bears-the Weight of said bolster, substantially as desupport resting on said spring springs and 4c end, and a swingingbail bearing the weight of said bolster and hung on said bolstersup port, a' portion of said bail fitting in the groove of said bolster, substantially described.

- 4. In a railway car truck, the combination of a side frame having abolster-and spring opening with substantially vertical straight margins constituting column portions of the side frame,

one -or-more springs, a bolster support resting on said spring or springs and having at each end a singl ada ted to cooperate with the inner surface of the adjacent column portion of the side frame, a bolster, and means bearing the weight of said bolster swingingly mounted e guiding rib on said bolster support, substantially as described. As evidence that- I claim the foregoing as my mvention, I have signed the same this 23rd day of November, A. D., 1907,-in the presence of two witnesses.
